Answer:

197200atm

Explanation:

There are different units to express pressure of a gas, some of them are atmosphere, Bar, Kilopascal, Pascal, torr among other.

In this exercise we need to know the equivalence between atm and Kpa.

if, 1kp=0,00986atm

then,

(2,000 x104kPa)*(0,00986atm)/1Kpa= 0,00986 atm

Answer:

197.4 atm is the Answer.

Explanation:

Pressure can be expressed in unit of torr, mm Hg, psi, atm, kPa etc

1 atm = 760 torr = 760 mm Hg = 14.7 psi = 101.325 kPa

So Here to convert atm to kPa the conversion factor is either $\frac {1atm}{101.325kPa}$ or $\frac {101.325kPa}{1atm}$

We need the answer in atm so kPa should get cancel and it should be in the denominator

$2.000 \times 10^4 kPa\times \frac {1atm}{101.325kPa}$

=197.4 atm is the Answer.

When iron(II) chloride reacts with silver nitrate, iron(II) nitrate and silver chloride are produced. The balanced equation for

kati45 [8]

Answer: The moles of silver nitrate reacted is 5.72 moles, moles of iron (II) nitrate produced is 2.86 moles and moles of silver chloride produced is 5.72 moles

Explanation:

We are given:

Moles of iron (II) chloride = 2.86 moles

For the given chemical equation:

$FeCl_2(aq.)+2AgNO_3(aq.)\rightarrow Fe(NO_3)_2(aq.)+2AgCl(s)$

For silver nitrate:

By Stoichiometry of the reaction:

1 mole of iron (II) chloride reacts with 2 moles of silver nitrate.

So, 2.86 moles of iron (II) chloride will react with = $\frac{2}{1}\times 2.86=5.72mol$ of silver nitrate

Moles of silver nitrate reacted = 5.72 moles

For iron (II) nitrate:

By Stoichiometry of the reaction:

1 mole of iron (II) chloride produces 1 mole of iron (II) nitrate

So, 2.86 moles of iron (II) chloride will produce = $\frac{1}{1}\times 2.86=2.86mol$ of iron (II) nitrate

Moles of iron (II) nitrate produced = 2.86 moles

For silver chloride:

By Stoichiometry of the reaction:

1 mole of iron (II) chloride produces 2 moles of silver chloride

So, 2.86 moles of iron (II) chloride will produce = $\frac{2}{1}\times 2.86=5.72mol$ of silver chloride

Moles of silver chloride produced = 5.72 moles

Hence, the moles of silver nitrate reacted is 5.72 moles, moles of iron (II) nitrate produced is 2.86 moles and moles of silver chloride produced is 5.72 moles

79. Methane, the chief component of natural gas, burns in oxygen according to the equation

Andrews [41]

Answer:

14 mol

Explanation:

CH4(g) + 2O2(g) -------» CO2(g) + 2H2O(g)

from reaction 1 mol 2 mol

given 7 mol x mol

x = (7*2)/1 = 14 mol

Is carbon dioxide formed during incomplete combustion of methane? ...?

dexar [7]

Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. The carbon is released as soot. Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.
